Here's another amp based on runoffgroove's wonderful Ruby -
http://www.runoffgroove.com/ruby.html.
The Ruby amp is great for knocking up cheap and cheerful creations when an idea strikes to build an amp out of something you've got lying around - a washing up bowl in this case - perhaps more accurately described as a tub, given the shape?
A side benefit of this kind of activity is always discovering something new that can be applied elsewhere. A bit of trial and error with the construction led to a new idea for covering/surfacing things that might be put to good use on other builds - perhaps a guitar or some furniture. Anyway, hopefully the pictures speak for themselves, with a few notes here and there.

A washing up bowl on legs with plywood face.

Retro style legs from an old clock resembling a TV, drawer handle and 9 volt socket affixed to bowl.

Ruby circuit and speaker mounted on fabric-wrapped plywood face.

The speaker grille is a rigid, fibrous mesh used by gardeners for potting. It's lacquered to the fabric-wrapped wood and the whole thing lacquered some more.

The look of yesteryear, the smell of tomorrow (or sometime in the future when the lacquer finally cures for good).

Turned out looking quite neat. I will use the lacquered fabric technique again.
